双馈型变速恒频风力发电机PI自适应控制的研究

Research on PI Adaptive Control of VSCF (Variable Speed Constant Frequency) Double-fed Wind-driven Generator

采用双馈发电机,针对其数学模型,结合模型参考自适应(MRAS)理论和PI自适应算法,构造了一种改进的无速度传感器双馈电机按定子磁链定向的矢量控制系统,指出该系统具有良好的稳态辨识特性和鲁棒性。

By using double-fed wind-driven generator,based on mathematic model of double-fed wind-driven generator,and connecting with MRAS（model reference adaptive system）theory and PI adaptive algorithm,this paper presents a modified vector control system of the speed sensorless control double-fed wind-driven generator based on the orientation of the stator flux,and points out that thethe system possesses excellent stationarity identification property and robustness.
